    Hubby was just reading an article in an older of backwoods home (i think) about using canvas for roofing and using exterior paint to water proof it... you might check out that idea... check out their web site. sorry I cant offer more, just remember hubby telling me about it.

    Please be very careful of what you use to waterproof your tent. Here we had a tragedy where there was a family with 4 kids and they had just waterproofed their tent. They used a spray can to do it. Then they went camping. With the kids inside it the tent burst into flames killing all but 1 of the kids. Those poor kids took days to die after that fire. It was incredibly sad and very preventable. Even tho it was years ago I still feel really bad whenever I think about it. Please be very careful!

    i believe the book "the indian tipi" describes how the Authors made their own canvas tipi cover... or was it a couple who own a modern tipi company? I cant remember, but, They describe painting the outer side of the canvas cover once a year with "seamans water seal" wood treatment... claimed the cover lasted almost 20 years comparred to 5-10. Also these were used with fire inside.

    Ugh, Thompson's water seal . . Tried that, got soaked the first time I went camping. The other alternative I knew of at that time was extremely flamable, so I didn't even try it (oil)

    I've used successfully for several years:
    exterior laytex paint, half & half with water
    theatrical flame retardant
    mildecide (for killing mildew, found it at Lowe's or Home Depot)
    Mix them all together & you'll be able to do everything in one coat. I used this on my pavillion that we camped in for six months. We'd also used the pavillion on probably a good couple dozen camping trips, some of them lasting as long a 2 weeks, the shorter end being a couple nights. You'll want to make sure to get the corners of the seams well (i.e., where I had the only leak in the tent was where about 6 seams all came together in heavy canvas).

    Hope that helps!
